There is no denying that these layoffs are coming. You obviously don't work at Target or aren't in touch with people that do. Right now productivity is at a standstill. Entire departments have boxed up all their belongings waiting for the day it is announced. I promise you that if nothing was planned leadership would have at, a minimum, informed KMG and to have them inform the team members.
The date of the 15th came from multiple target team members before I saw it posted here. Granted, it's all a rumor mill anyway and if anyone here is looking for a real leak, they are kidding themselves.
